[Elecraft] K3 -> SteppIR communication

[Jim Spears]

Thanks to all who have chimed in with suggestions.  At this point the setup
is as follows:

 

K3 at any of 4800, 9600, 19200, 38400 bps

K3 with CONFIG:  AUTOINF = "AUTO 1" or "norm"

SteppIR set to "KENW" mode, LED 6 set when Select is held for 2 or 3 seconds

SteppIR Y cable connecting K3 to PC serial port with other leg of Y going to
SteppIR Data In port

Ham Radio Deluxe software running

 

HRD will connect to K3 and follow frequency, band, and mode changes at any
data rate

 

SteppIR will not follow K3 at any data rate

 

RS232 tester shows RTS (pin 7) set all the time as is expected with cable
wiring

Also shows RD (pin 2) data present as K3 frequency and band change

 

I suppose I could feed the Y cable leg into a terminal program and verify
the data coming into the SteppIR

 

Right now it looks to me that the interface board on the SteppIR controller
is the culprit.  Any suggestions?
